Be .it known that I, HAROLD H. HOR'roN, a subject of the King of Great Britain, and

a resident of the city of New York,bor ough of Manhattan, in the county and State of New York, have invented anew and Improved Portable F ilmeDrying D`rum,'of

which the following is a full, clear, and

y exact description.

arranged in a small bodyfor transporta- This inventionfrelates to film dryingde'- vices and particularly to an improved'portable film drying drum-and lhas for an object to provide a construction which may be quicklya'ssembled and disassembled so "that at one time it will actin the desired man ner for supportinga' film 'and another to be tion or st oragei Another object of the invention is to pro-V vide a portable dryingdrumfin which various" parts are formedlsoqas to be quickly? assembled and disassembled fand vby their shape to be held. rigidly in place wlfienf'as-A sembled.

Figure 4 is a perspective view showing the cross bars forming one end' of the drum shown in Figure 1.

vFigure 5 is the central or main shaft shown in Figure 1.

Figure 6 is a perspective view of one of the film carrying bars.

Referring to the accompanying drawings y by numeral, 1 indicates a box provlded with y a lid 2 hinged to box 1 with suitable hinges 3 normallyr held closed by a liasp 4. The

l box 1 acts as a container for receiving the reel when disassembled and acts as a base for supporting a rail when assembled as shown in Figures 1 and 2. In order to properly support the reel when assembled the lid 2 is rovided with cleats 5 at each end arrange opposite the openings 6 at each end through which a rectangular reduced extension 7 of the respective posts 8 and 9 extend. Y

As `shown in Figure 1, when the extenheld firmly' in position. The upper'bnd f eachof the p'o'sfts 8 is provided with anV ape tureflO for receiving theV and 12 of the central shaft 13` whereby said shaft may freely rotate in said supports.

' Each endl of the 'shaft 18 is provided 'with' a squared reduced section 14 which projects' through'l the squared openings 15 and 16 of the respective b'a'rsff` and 18a-teach end ofthe reel Bars V17 yand 18'for'm'the ends' of the drum an'dffarejnotched at 19 and 201 y so that they may' interlock as"'shown'in Fig-V ure l and the squared section '14'properly fit y1n the apertures -155 and 161'] By this ar-y rangement, 'bar 18 'presses against vthe Sh'oul-v` de r 21`Whi-lefthe' bar' 17 frictionallyegag's a spacingwasherf22` Whichfis 'arrarigedA lbfe-` tween bar'k 17 :and the reectivev standards s Aande 'is illustrated-fia gare" 1p1-fini this way', the 'felidfp'ieces .orfb'arsiare out the use of direct fastening means, Each of the bars 17 and 18 at the respective. ends of the drum is provided with a series of rectangular openings 23-'for receiving the ing Vbarsl26. When any of these parts are placed in position, the 'end 25 is first inserted until theshoulder 27 has engaged the end supporting bars 17 and` 18. In the opposlte portion 24 it is forced into the opposite bar 17 or' 18 as the case may be,V which forcing action will partially withdraw thev rectangular section 25. Suitable pins 28 and 29 are then inserted through the respective apertures 30 and 31 in sections 24and 25. This will lock the bar in position and against independent rotation.

Each of the supporting bars 26 is provided.

with spaced pins 32, said pins extending preferably radially of the drum and acting to hold the various layers of film 33 apart.

It will be noted in Figure 6 that the edge of thebearing 26 carrying the pins 32 is rounded and, consequently, presents ay nice easy support for the film. Preferably, when the drum is first assembled as shown in Figure l the inner series of bars 26 is inserted and the film rolled thereon until .these bars have been filled, after which a second row or third row. It is evident that more or rounded ends 11' M Liirpiiflyinterloekedand held rigidly togethe'riwitb PATENT orrlc.

Vof bars are provided and finally the outer 85 n rectangular ends 24 and 25 of the'film carryf.

even less rows of bars could be used than shown in the drawing Without departing from thespirit ofthevinvention.
